LUKE CHAPMAN, OF COLLlNSVILLE, CONNECTICUT, ASSIGNOP. OF ONE-HALF OF HIS RIGHT TO THE COLLINS COMPANY, OF SAME PLACE.

PLOW.

SPECIFICATION forming part of Letters Pateft No. 223,580, dated Januaryls, 1880. Application filed November 20, 1879.

To all whom it may concern Be it known that I, LUKE CHAPMAN, ot Collinsville, bin the county of Hartford and State of Connecticut, have invented `a certain new rand useful Improvement in Plows, ot' which the following is a description, reference being had to the accompanying drawings, Where- Figure 1 is a side view showing the face of the share and mold-board. Fig. 2 is a side view showing the opposite side. Fig. 3 is a top view with a portion of the'standard broken Fig. 5 is a rear view.

The invention relates to such a construction of the share, mold-board, and land-side ofv a plow, and in such aunion thereof, through the medium of a uniting-piece, that no necessity exists for the appearance of bolts or screws or holes therefor' on the working-tace ot' the plow. v

The invention is an improvement upon that class of plows which have inwardly-projecting flanges, by which the parts are united, the improvement consisting in uniting` the iianges ot' the mold-board, share, and land-side by means of' a plate ot' metal bolted thereto, as hereinafter specified.

The lettera denotes the mold-board, bearing the flange a', integral therewith. b denotes 3o the share, bearing the iiange b', integral therewith. c denotes the land-side, bearing the Harige c', integral therewith. d denotes a uniting-piece, which I term a flange-base, extending from the flanges afb to the flange c', 35 all of which are secured thereto by bolts or the like. These several langes extend horizontally inward from their respective bearingbodies, and substantially in line one with theV other, the mold-board flange resting upon the 4o shai'e-liange, so that when bolted to the Hangebase a close joint will be formed.

The standard e is shown as attached by` bolts to awingprojecting from the moldboard. A modiiication is to attach it wholly or partly 45 to the iiange-base.

I claim as my invention- The combination of the mold-board a', with its ange a', the share b, with its iiange b', the land-side c, with its ange c', and the independ- 5o ent or separate {jauge-base d, supporting and connecting the other parts, substantially as shown and described.
